 assuming that this:
 https://svn.boost.org/svn/boost/trunk/boost/ptr_container/ is the correct
 repository, the compiler can't find push_back(), push_front(), begin(),
 and end(). E.g:
 ‘class boost::ptr_list<BASE, boost::heap_clone_allocator,
 std::allocator<void*> >’ has no member named ‘begin’

 I didn't reinstall the entire library, but just downloaded ptr_container
 and used rest of old library. I don't think this is problematic b/c I
 tested 1.39.0 the same way and it works fine.

 Just to make sure that the const issue isn't one that was fixed by 1.39.0,
 I tested it as well and it has the same problem w/ ptr_list not compiling
 w/ const items.

 I should mention that in the code where I'm using ptr_list I've already
 switched over to non-const items in ptr_list. (B/c of abstraction there
 isn't a way to accidentally tweak the internals of the object, but const
 would be the theoretical ideal)

 Before you go changing code, are the objects in ptr_list supposed to be
 non-const by design?
